Great photos and a great airplane, takes me back to a few years ago (2007 i think) I heard the most terrific din over the skies above my flat, the building was shaking!
I opened the back door just in time to see a Spitfire and Hurricane trailed by a Lancaster!
Turned out to be the VE day memorial flight. The best surprise airplane I sighting I can remember.

Mind you I spotted a civilian looking Russian Mi-17 over Hyde park in January, not sure what that was about! it was unmistakable though, the bloody thing looks like a house with rotor blades. Maybe Putin was in Town
